Description

Technical Field

[0001] The invention belongs to the technical field of extraction devices, and in particular relates to a lifting device for a wire guide roller of an extraction machine. Background Art

[0002] At present, the main function of the extractor of the special fiber post-processing equipment in the textile industry is to extract the white oil from the tow with an extractant (dichloromethane / tetrachloroethylene, etc.) in the extraction tank; for the convenience of operation, a driven wire guide roller (also called an active roller) is provided above the liquid surface of the extractant in the extraction tank, and the tow enters the extraction tank through the upper part of the active roller. A driven wire guide roller (also called a lifting roller) that can be raised and lowered is provided above the active roller at the top of the extraction tank. The lifting roller descends to press the tow below the liquid surface of the extractant to achieve the purpose of extracting the white oil.

[0003] At present, the lifting rollers of the existing extractors are all pneumatically lifted and lowered, and the lifting rollers are lifted and lowered. The problems existing in these devices are as follows: 1. Pneumatic lifting requires the cylinder rod to extend below the liquid level of the extractant, and the extractant is highly corrosive, which will damage the surface of the rod and the cylinder seal, causing unstable cylinder pressure; 2. When the pressure is high, the cylinder extends too quickly, and the tow is easily broken, or the cylinder retracts too quickly, and the tow is loose and knotted or entangled with the roller; when the pressure is low, the tow cannot be pressed below the liquid level of the extractant; 3. The cylinder cannot stop at any position during the lifting and lowering process, and the length of the tow entering below the liquid level of the extractor cannot be arbitrarily controlled; 4. When one side of the cylinder is damaged, leaking or faulty, the tow has a large pulling force, which is easy to damage the equipment and other defects, and it is also easy to cause the extractant to volatilize. The extractant is a toxic chemical reagent that affects environmental health; 5. Usually because of the large lifting stroke, the pulling force of the tow will cause the lifting roller to swing, causing defects such as tow doubling, affecting the quality of the tow. Summary of the invention

[0004] In view of the above problems, the present invention provides an extraction machine wire guide roller lifting device, which is used to solve the problems that the existing lifting device is easily corroded by the extractant, the operation is unstable, the stroke is large, it is not convenient to stop halfway, and the wire guide roller is prone to tilt and swing, resulting in easy breakage of the wire bundle.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A lifting device for a wire guide roller of an extraction machine comprises a containing box, a first guide piece is fixedly arranged above the containing box, the wire guide roller is accommodated in the containing box, a sleeve rod is connected above the wire guide roller and is slidably arranged with the first guide piece, a threaded rod is connected to the inner thread of the sleeve rod, and a driving source is connected to the threaded rod;

[0007] The lower end of the sleeve rod is sealed, and an adjusting mechanism for adjusting the position of the wire guide roller and slidably arranged with the first guide member is arranged on the outer side of the sleeve rod.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: a first guide member is provided to provide a vertical up and down lifting guide movement to avoid shaking during the lifting process and maintain the stability of the lifting, and a threaded drive method is used to achieve a stop at any position; a sleeve rod and a threaded rod are provided, and the lower end of the sleeve rod is sealed, so that after the rise, the volatilization of the extractant from the gap to the outside can be reduced to ensure environmental safety; the adjustment mechanism can adjust the extension position between the sleeve rod and the threaded rod, so that the sleeve rods on both sides of the wire guide roller can be lifted and lowered by the same amount, so that the wire guide roller can work in a horizontal state, so as to avoid the wire guide roller from tilting and swaying, and prevent the wire bundle from breaking during extraction.

[0009] As a further improvement of the above scheme, the adjustment mechanism includes a slide seat fixed to the top of the sleeve rod and slidably arranged with the first guide member, a spline sleeve is fixedly arranged above the slide seat, and a threaded sleeve threadedly connected to the threaded rod is splined in the inner cavity of the spline sleeve;

[0010] An external sleeve is fixedly arranged outside the threaded sleeve, and an adjusting knob is respectively threadedly connected on the external sleeve and the spline sleeve.

[0011] As a further improvement of the above solution, a blocking member is fixedly provided on the top of the spline sleeve to prevent the threaded sleeve and the spline sleeve from being separated from each other.

[0012] The technical effect of the above improvement is: by rotating the adjusting knob, the spline sleeve and the external sleeve can be driven to move in the same direction or in opposite directions, so as to adjust the upper and lower positions of the spline sleeve. Therefore, when the wire guide roller is tilted and deflected, the upper and lower extension positions of the sleeve rod can be changed by rotating the adjusting knob, so as to make the wire guide roller level.

[0013] As a further improvement of the above solution, the wire guide roller is rotatably arranged below the support seat, and the top of the support seat is connected to the lower end of the sleeve rod;

[0014] The lower end of one of the sleeve rods is hinged to the support seat, and the lower end of the other sleeve rod is provided with a connecting pin, which is connected to the connecting seat on the top of the support seat. The connecting seat is also provided with a movable groove that facilitates the mutual swing of the support seat and the sleeve rod, and the connecting pin moves within the range limited by the movable groove.

[0015] The technical effect of the above improvement is: the movable groove can make the connecting pin move within a limited range, so when the position of the sleeve rod moves up and down, the inclination state of the wire guide roller is adjusted, and the movable groove can avoid interference during adjustment.

[0016] As a further improvement of the above solution, extension columns extending outward are fixedly provided at both ends of the support seat, and rollers are rotatably provided on the extension columns;

[0017] An extraction box is arranged below the containing box, a plurality of second guide members contacting the rollers are arranged on the inner wall of the extraction box, and a limiting member for limiting the extension column is arranged at the lower end of the second guide member.

[0018] The technical effect of the above improvement is: the second guide member can limit the roller when the wire guide roller moves downward, thereby avoiding the unstable shaking of the end due to the long stroke, and the limit member can limit the extension column to maintain the stability of the wire guide roller in guiding the wire bundle during extraction.

[0019] As a further improvement of the above solution, an isolation door is hingedly provided on the inner cavity wall of the storage box, and a limit plate is also provided on the inner wall of the storage box to prevent the isolation door from flipping upward excessively. A magnetic suction part is fixed on the limit plate to absorb the isolation door to keep the isolation door closing the lower opening.

[0020] As a further improvement of the above scheme, a plurality of support pins are fixedly arranged on the inner cavity side wall of the containing box, and a pull wire with two ends respectively fixed to the isolation door is wound around the support pin. When the wire guide roller moves upward, the extension column hooks the pull wire to pull the isolation door upward to close.

[0021] A driving member is also provided between the isolation door and the containing box to drive the isolation door to flip downward, and the downward flipping force provided by the driving member is smaller than the suction force of the magnetic member on the isolation door.

[0022] The technical effect of the above improvement is: through the setting of the containing box, the wire guide roller can be stored in a relatively closed space, and the isolation door can be pulled upward and closed when the extension column pulls the pull wire when the wire guide roller moves upward, and it continues to remain closed under the adsorption of the magnetic suction part, so that the residual extractant on the wire guide roller and the support seat can be isolated in the containing box when it evaporates, thereby avoiding the volatilization of the extractant to the outside, reducing the overflow of toxic gases, and playing a protective role.

[0023] As a further improvement of the above solution, a guide piece is fixedly provided at the end of the extension column and contacts the inner wall of the receiving box so as to facilitate the pull wire to be hung on the extension column.

[0024] The technical effect of the above improvement is: the guide plate is mainly provided to facilitate the pull wire to be smoothly hung on the guide plate, so that it can be ensured that when the wire guide roller moves upward, the pull wire can be smoothly pulled through the extension column to close the isolation door.

[0025] As a further improvement of the above solution, the support seat is provided with a mounting seat with an opening facing downward, and a limiting sleeve is fixedly mounted on the mounting seat;

[0026] The end of the wire guide roller is sleeved with a shaft sleeve, and a rotating member is sleeved on the outer side of the shaft sleeve. The rotating member rotates in the limiting sleeve. A baffle is also fixedly arranged at the end of the wire guide roller to prevent the rotating member and the shaft sleeve from detaching.

[0027] The technical effect of the above improvement is: by adopting the method of mutual rotation between the rotating part and the limiting sleeve, the entire outer edge of the rotating part can be in a state of wear during long-term operation, thereby avoiding direct wear of the wire guide roller, saving costs, and reducing the problem of inclination of the wire guide roller caused by wear.

[0028] As a further improvement of the above solution, an air inlet pipe for blowing air into the containing box is provided on one side wall of the containing box, and a plurality of air injection pipes arranged toward the middle are connected to the air inlet pipe;

[0029] An exhaust pipe is also arranged on the other side wall of the containing box to facilitate the extraction of air in the containing box.

[0030] The technical effect of the above improvement is: by blowing air into the containing box, the volatilization of the residual extractant on the wire guide roller and the support seat can be accelerated. At the same time, an exhaust pipe is provided to absorb the volatilized extractant outward, reducing the residue in the air, so that the containing box can be easily inspected and maintained to avoid poisoning of personnel.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0047] like Figure 1-14As shown, the specific scheme of this embodiment is: a lifting device for a wire guide roller of an extraction machine, comprising a accommodating box 10, a first guide member 11 is fixedly arranged above the accommodating box 10, the first guide member 11 is a plurality of guide columns, a wire guide roller 12 is accommodated in the accommodating box 10, a sleeve rod 13 which is slidably arranged with the first guide member 11 is connected above the wire guide roller 12, a threaded rod 14 is connected to the sleeve rod 13 with an internal thread, a driving source is connected to the threaded rod 14, the driving source is a set motor, the motor and the first guide member 11 are fixedly arranged, and the output shaft and the threaded rod 14 are transmission-connected, so when the motor drives the threaded rod 14 to rotate, the sleeve rod 13 can be driven to move up and down, and under the guidance of the first guide member 11, the stability of the lifting process is maintained, refer to the attached Figure 4 ;

[0048] The lower end of the sleeve rod 13 is sealed, and an adjustment mechanism for adjusting the position of the wire guide roller 12 and slidably arranged with the first guide member 11 is provided on the outer surface of the sleeve rod 13; by sealing the lower end of the sleeve rod 13, it is possible to prevent the extractant from entering the sleeve rod 13 when the sleeve rod 13 is extended downward into the extractant, thereby isolating the extractant from the installation gap between the sleeve rod 13 and the threaded rod 14 to prevent it from volatilizing from the installation gap. The adjustment mechanism can adjust the extension length of the sleeve rod 13 so that the wire guide roller 12 can be in a horizontal state to perform wire guiding work;

[0049] An extraction box 18 is disposed below the containing box 10 . The extraction box 18 is filled with an extractant and a water seal layer located above the extractant. An opening is disposed below the containing box 10 and is interconnected with the extraction box 18 .

[0050] like Figure 4 , 12 As shown, as a preferred embodiment of the above embodiment, the adjustment mechanism includes a slide seat 132 fixed to the top of the sleeve rod 13 and slidably arranged with the first guide member 11, a spline sleeve 133 is fixedly arranged above the slide seat 132, a threaded sleeve 134 threadedly connected to the threaded rod 14 is splined in the inner cavity of the spline sleeve 133, and the spline sleeve 133 and the threaded sleeve 134 are splined to each other, so that the threaded sleeve 134 can be prevented from rotating with the threaded rod 14, thereby limiting the rotation of the threaded sleeve 134;

[0051] An external sleeve 135 is fixedly arranged on the outside of the threaded sleeve 134, and an adjusting knob 136 is threadedly connected to the external sleeve 135 and the spline sleeve 133 respectively. Specifically, the threads connecting the adjusting knob 136 and the external sleeve 135 and the spline sleeve 133 are threads of opposite rotation directions. Therefore, when the adjusting knob 136 is rotated, the position between the external sleeve 135 and the spline sleeve 133 can be changed, thereby adjusting the downward extending length of the sleeve rod 13 to facilitate adjusting the horizontal state of the wire guide roller 12. A fastening bolt is arranged on the outside of the adjusting knob 136. After the position of the sleeve rod 13 is adjusted to a suitable distance, the fastening bolt can be tightened to fix the position between the adjusting knob 136 and the slide seat 132.

[0052] As a preferred embodiment of the above embodiment, a blocking member 137 is fixedly provided on the top of the spline sleeve 133 to prevent the threaded sleeve 134 and the spline sleeve 133 from being separated from each other. Fig.12 As shown, the blocking member 137 is an annular structure, which is fixed to the top of the spline sleeve 133 by bolts to limit the upward separation of the threaded sleeve 134.

[0053] like Figure 2 , 6 , 7, 8, 9, 11, 13, and 14, as a preferred embodiment of the above embodiment, the guide roller 12 is rotatably arranged below the support seat 15, and the top of the support seat 15 is connected to the lower end of the sleeve rod 13;

[0054] The lower end of one sleeve rod 13 is hinged to the support seat 15, and the lower end of the other sleeve rod 13 is provided with a connecting pin 131, which is connected to the connecting seat 151 at the top of the support seat 15, and the connecting seat 151 is also provided with a movable groove 152 for facilitating the swing of the support seat 15 and the sleeve rod 13. The connecting pin 131 moves within the range defined by the movable groove 152. Figure 7 , 8 Therefore, through the hinge setting between one of the sleeve rods 13 and the support seat 15, the other sleeve rod 13 and the support seat 15 can move within the range limited by the movable groove 152, so that when the upper and lower positions of the sleeve rod 13 are adjusted, the sleeve rod 13 and the support seat 15 can swing around the position of one hinged end, which is beneficial to adjust the support seat 15 and the wire guide roller 12 to a horizontal working state and avoid the wire guide roller 12 from tilting. The structure of the movable groove 152 can avoid interference during adjustment.

[0055] The two ends of the support seat 15 are fixedly provided with extension columns 16 extending outward. Specifically, the support seat 15 is provided with a mounting seat 153 with an opening facing downward, and the extension column 16 is fixedly provided on the mounting seat 153. A roller 17 is rotatably provided on the extension column 16. Figure 6 ,9 , as shown in 11; a plurality of second guide members 19 in contact with the roller 17 are arranged on the inner wall of the extraction box 18, and the second guide members 19 are specifically arranged as guide grooves, and a limiting member 20 for limiting the extension column 16 is arranged at the lower end of the second guide member 19, and the limiting member 20 is a limiting block. When the sleeve rod 13 drives the support seat 15 and the guide roller 12 to move into the extraction box 18, it first contacts the roller 17 under the guidance of the second guide member 19, and the roller 17 can be limited, thereby avoiding the shaking and unstable position of the guide roller 12 and the support seat 15 due to the increase in stroke.

[0056] The limiting sleeve 30 is fixedly mounted on the mounting seat 153. The mounting seat 153 is a plate-shaped structure with an opening facing downward and in a "C" shape. The limiting sleeve 30 is fixed to the mounting seat 153 by bolts. Figure 6 The end of the wire guide roller 12 is sleeved with a shaft sleeve 33, and a rotating member 31 is sleeved on the outer side of the shaft sleeve 33. The rotating member 31 rotates in the limiting sleeve 30, and the end of the wire guide roller 12 is also fixedly provided with a baffle 32 to prevent the rotating member 31 and the shaft sleeve 33 from detaching. The baffle 32 is fixed to the end of the wire guide roller 12 by bolts and is specifically in the shape of a plate. It plays a blocking role for the rotating member 31 and the shaft sleeve 33 to prevent detachment, and a boss protruding outward is provided on the baffle 32, and a notch for accommodating the boss on the baffle 32 is also provided on the rotating member 31, so that the positions of the rotating member 31 and the baffle 32 can be fixed to each other to avoid friction caused by rotation. By providing the mounting seat 153 and the limiting sleeve 30, the wire guide roller 12 can be easily disassembled when it is inspected and replaced. The rotating member 31 can reduce the wear on the wire guide roller 12, thereby avoiding problems such as tilting of the wire guide roller 12 when used for a long time, and reducing the cost of replacing the wire guide roller 12.

[0057] like Figure 1 , 2 As shown in FIGS. 3, 5 and 10, as a preferred embodiment of the above-mentioned embodiment, an isolation door 21 is hingedly provided on the inner wall of the container box 10, and a limit plate 22 is also provided on the inner wall of the container box 10 to prevent the isolation door 21 from excessively turning upward. Fig.10 A magnetic attraction member 23 is fixedly provided on the limiting plate 22 to attract the isolation door 21 to keep the isolation door 21 closing the lower opening. The magnetic attraction member 23 is specifically a permanent magnet.

[0058] A plurality of support pins 24 are fixedly disposed on the inner side wall of the container 10. Figure 3, a pull wire 25 is wound around the support pin 24, and the two ends are respectively fixed to the isolation door 21. When the wire guide roller 12 moves upward, the extension column 16 hooks the pull wire 25 to pull the isolation door 21 upward to close; a driving member for driving the isolation door 21 to flip downward is also provided between the isolation door 21 and the receiving box 10, and the downward flipping force provided by the driving member is less than the suction force of the magnetic member 23 on the isolation door 21. Specifically, the driving member can be a spring or a torsion spring, etc., which mainly provides the force to pull the wire guide roller 12 downward. In this embodiment, a torsion spring (not shown in the drawings) is selected;

[0059] When the isolation door 21 is opened and closed, it is controlled by the up and down movement of the wire guide roller 12. For example, when the isolation door 21 is closed, the wire guide roller 12 should be located inside the containing box 10. Therefore, when the wire guide roller 12 moves upward under the drive of the sleeve rod 13, the extension column 16 hooks the pull wire 25 upward, and while continuing to move upward, the pull wire 25 is pulled to close the isolation door 21 upward. At this time, it is adsorbed by the magnetic element 23 to achieve self-locking. When the isolation door 21 needs to be opened, it is pushed downward by the wire guide roller 12, that is, when the threaded rod 14 moves downward, it drives the wire guide roller 12 to push the isolation door 21 downward to push the isolation door 21 to swing downward. At this time, the suction force of the magnetic element 23 is not enough to adsorb the isolation door 21, and it opens downward under the push of the torsion spring and the isolation door 21's own gravity.

[0060] In addition, in order to enable the extension column 16 to move upward and accurately hook the pull wire 25, the end of the extension column 16 is also fixedly provided with a guide piece 29 that contacts the inner wall of the receiving box 10. The guide piece 29 can make the pull wire 25 slide smoothly onto the extension column 16. Figure 6 .

[0061] In order to reduce the danger caused by the extractant, an air inlet pipe 27 for blowing air into the containing box 10 is provided on one side wall of the containing box 10, and a plurality of air jets 26 arranged toward the middle are connected to the air inlet pipe 27; the air blown from the air jets 26 is blown onto the godet roller 12 and the support seat 15, so that the extractant remaining on the surface thereof can be quickly volatilized to reduce the residue; an exhaust pipe 28 for conveniently extracting the air in the containing box 10 to the outside is also provided on the other side wall of the containing box 10, and a suction pump can be connected to the exhaust pipe 28, so that the extractant existing in the containing box 10 can be extracted to the outside through the exhaust pipe 28, and the bottom of the containing box 10 is closed by the isolation door 21, so as to reduce the diffusion of the extractant, thereby facilitating its removal;

[0062] Secondly, another reason for setting up the containing box 10 is to replace and repair the wire guide roller 12. Specifically, blind holes 34 are set on both sides of the containing box 10, and the blind holes 34 can be opened and closed. When repairing, the blind holes 34 are opened and the wooden squares 35 are inserted to support the wire guide roller 12. At this time, repair can be carried out. Therefore, for the safety of repair, the extractant on the wire guide roller 12 needs to be cleaned in advance to avoid poisoning of personnel.
